- Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
- Users make sure they have installed USB drivers on the PC, or else your phone (Google Nexus 4) smartphone will not be recognised by the computer.

- Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
